For example, some common austenitic stainless steels are marked with ,tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd , and ferritic stainless steels are marked with and , martensitic stainless steels are marked with and C, duplex (austenitic ferrite), stainless steels, precipitation hardening stainless steels and high alloys with iron content less than % are usually named by patent name or trademark.

YlThe width of coiled material is variable, etc. it can also be divided according to customer requirements

Stainless steel pipe will rust? It will rust. The stainless steel pipe only means that it is not easy to rust, which does not mean that it will not rust. If it is placed in seawater, it will still be embroidered soon. It will not rust at room temperature. If it is in a high sulfate alkali environment for a long time, it will produce spot rust. It will not rust under normal circumstances, except in places with acid rain. Stainless steel pipe itself will not rust, but improper use and maintenance will cause & ldquo; Floating rust& ldquo; Mildew & rdquo; And other undesirable phenomena.


The specification and appearance quality shall comply with the provisions of gb- stainless steel seamless steel pipe. The steel pipe is usually ~ m long (indefinite length) hot rolled steel pipe, and the hot extruded steel pipe is equal to or greater than m. The wall thickness of cold drawn (rolled) steel pipe is . ~ mm, ~ m; the wall thickness is greater than mm, ~ m.

Fproperty rightIn order to obtain seamless pipes with smaller size and better quality, cold rolling, heat exchanger and pipe fittings.

The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK) in which the carbon content is represented by the intermediate value & times; , the letter C: represents carbon, and K: represents steel for carburizing. For example, the carbon content of carbon coil sc is .-.%. The grades of silicon steel sheets in China and Japan are.


Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA), MPa is called MPa, equal to n (Newton) / mm (MPA = pa, PA: Pascal = n / M

Pricev(III) steel exports grew rapidly. The supply and demand of domestic steel market is unbalanced, and the export of enterprises. From January to June, China exported . million tons of steel, a year-on-year increase of %; . million tons of steel were imported, down %, and tons of billets and ingots were imported, up %. Converting billets into crude steel, the cumulative net export was . million tons, a year-on-year increase of %, the average export price of bars and wires from January to June was US dollars per ton, a year-on-year decrease of %.

PAs long as the steel type is selected correctly and maintained properly, stainless steel will not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the metal materials with high strength. Because stainless steel has good corrosion resistance, it can keep the integrity of engineering design of structural components. Chromium containing stainless steel also integrates mechanical strength and high extensibility, which is easy to process and manufacture parts, and can meet the needs of architects and structural designers.

Ti-a alloy with improved titanium and overall corrosion resistance has been used to manufacture u and Pu solution evaporation boilers and heat recovery evaporation boilers in Donghai reprocessing plant, Japan. In addition, zirconium is used in its continuous dissolution tank in the reprocessing plant in liusuo village, Aomori County, Japan. The U.S. Court ruled that the countervailing duty is not suitable for products from non market economy countries, which has just given Chinese steel pipe enterprises a little relief. The anti-dumping stick from the European Union has dealt a heavy blow to hundreds of domestic stainless steel pipe manufacturers.

kB cold rolling shall be subject to heat treatment, pickling or similar treatment, and then leveled to obtain appropriate gloss.

kX: stainless steel pipe: seamless pipe and seamless pipe (longitudinal welded pipe, decorative pipe, welded pipe, welded pipe, bright pipe). There are more than kinds of standard specifications of stainless steel pipe, all sizes, and the small pipe is more expensive, especially the capillary. The capillary is poor to be made of material, otherwise the pipe is easy to burst. You can also customize non-standard pipes for customers. Seamless pipes are mainly used in industry, and the surface is foggy, Not bright. The surface of the slotted pipe is a bright surface, and there is a thin welding line in the pipe, commonly known as welded pipe, which is mainly used for decorative materials. In addition, the pressure resistance of industrial fluid pipe depends on the wall thickness. and S are high temperature resistant pipes. They can be used normally below degrees, and the high temperature resistance can reach degrees

If the thickness of the steel plate is not enough, the professional sales of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are strictly tested and the quality is guaranteed. The preferential activities are in progress. Welcome to consult. It is easy to bend, which will affect the production of decorative plate. If the thickness is too large and the steel plate is too heavy it will not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation. At the same time, the allowance that should be left during processing or use of stainless steel plate shall also be considered. The thickness of copper plate is not absolutely consistent, but the thickness of the same steel plate shall be as consistent as possible. Generally, for medium-sized saw plate, the thickness tolerance is .-.mm. If the requirements are too strict, it is a structural steel plate with high resistance and hardness. The greater the mechanical damage resistance, the longer the service durability
